Edelbrock Thunder Series AVS Carburetors

The Best "Street Performance" Carburetor

Edelbrock engineers have made a great carburetor even better. The new and exciting Thunder Series AVS carbs are designed and calibrated to deliver optimum street performance in hundreds of applications--they are undeniably the most innovative and dependable street performance carburetors available today.
AVS stands for Adjustable Valve Secondary, which means just that--you have the ability to adjust the secondaries with simple tools (no springs required).You can use a late opening for heavy vehicles with higher gears or an early opening for light vehicles with lower gears.
For unmatched street performance, combine these carburetors with Edelbrock Performer, Performer Air-Gap, Performer EPS, Performer RPM, RPM Air-Gap, or Torker II manifold and camshaft combinations.

Thunder Series AVS Carburetors:

All the same advantages of the Edelbrock Performer Series, such as factory-set float levels for infrequent adjustments, 2-step metering rods for independent tuning of cruise and power circuits, and the ability to change jets, adjust floats, or replace needles without draining fuel

Qwik-Tune secondary air valve

A sturdy 2-piece body with no power valves to blow and no gasket below the fuel level for leak-free operation

CNC-machined and profiled front face delivers a smooth, custom look
